Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a composite thermal insulation wall panel for steel structure buildings. Background Technology

[0002] Steel structure buildings, primarily constructed of steel, are one of the most common structural forms in modern construction engineering. Their main load-bearing components, such as steel beams, columns, and trusses, are connected by welding, bolting, or riveting, offering significant advantages. First, steel's high strength and light weight allow for larger building spans and a lighter overall structure, effectively reducing foundation load and increasing usable space. Second, steel's good toughness and uniform material properties result in high structural reliability and particularly outstanding seismic performance. Furthermore, steel structure components facilitate industrialized production and on-site assembly, significantly shortening construction time and aligning with green building principles.

[0003] However, existing steel structure building walls typically use polystyrene, polyurethane, rock wool, etc., as the core material for wall panels. While these materials offer some insulation, further improvements and upgrades are needed to enhance the energy-saving performance of green buildings. Furthermore, gaps easily appear between adjacent wall panels after installation, leading to poor sealing, leakage, and reduced insulation performance. Therefore, a composite insulation wall panel for steel structure buildings is needed to address these issues. Utility Model Content

The metal surface layer one and metal surface layer two located on the right side of the inner layer structure form a connecting groove by bending and combining, and the metal surface layer one and metal surface layer two located on the left side of the inner layer structure form a connecting protrusion by bending and combining, and the connecting protrusion and the connecting groove can be inserted and matched. The inner layer structure includes vacuum thermal insulation material and Class A fireproof insulation board. The Class A fireproof insulation board is a rock wool board or glass wool board. The vacuum thermal insulation material and the Class A fireproof insulation board are bonded together.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention effectively improves the thermal insulation, sound insulation, and earthquake resistance of steel structure building wall panels by bonding vacuum thermal insulation material with rock wool board or glass wool to form the inner layer structure of the wall panels. Furthermore, the connection stability of the wall panels is improved by bending the first and second metal surface layers to form connecting grooves and connecting protrusions, and the sealing performance of the wall panel connections is enhanced by setting non-metallic sealing strips, thereby further improving the thermal insulation and waterproof performance of the steel structure building wall.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-4 The present invention provides the following technical solution: A composite thermal insulation wall panel for steel structure buildings includes an inner structure 1 and two metal surface layers 2 and 3 respectively bonded to the front and rear ends of the inner structure 1. The inner structure 1 is bonded to the metal surface layers 2 and 3 using a two-component polyurethane sealant. This bonding method is simple to implement and provides a strong and stable bond. The metal surface layers 2 and 3 serve as the outer protective layer of the wall panel, exhibiting good corrosion resistance and impact resistance, while also providing a decorative function.

[0023] The metal surface layer 2 and metal surface layer 3 located on the right side of the inner structure 1 form a connecting groove 4 by bending and combining. The metal surface layer 2 and metal surface layer 3 located on the left side of the inner structure 1 form a connecting protrusion 5 by bending and combining. The connecting protrusion 5 and the connecting groove 4 can be inserted and matched. With the setting of the connecting groove 4 and the connecting protrusion 5, the wall can be installed by insertion and matching during the construction of the wall, making the connection between the wall panels more stable.

[0024] In Embodiment 1 of this utility model, the bending shapes of metal surface layer 2 and metal surface layer 3 are as follows: Figure 1-4 As shown, the wall panel has two connecting protrusions 5, and after the two wall panels are connected, a space is left in the middle of the connection point. This space can accommodate the upper end of the bolt, preventing the upper end of the bolt from being exposed and improving the aesthetics of the wall panel installation. In embodiment 2 of this utility model, the bending shapes of the metal surface layer 2 and the metal surface layer 3 are as follows: Figure 5-6 As shown, the connecting groove 4 of the wall panel is U-shaped, which facilitates insertion and installation, and makes bending processing of the metal surface layer 2 and the metal surface layer 3 easy, thereby reducing the production cost of the wall panel. This invention is not limited to the two connection structures described above, but also includes other forms of connecting groove 4 and connecting protrusion 5.

[0025] The gaps formed by the bending of the inner structure 1 with the metal surface layer 2 and the metal surface layer 3 are filled with thermal insulation filler 6. The thermal insulation filler 6 is polyurethane or rock wool strip filler. By filling the irregular structure formed by bending the metal surface layer 2 and the metal surface layer 3 with polyurethane or rock wool strip filler, the thermal insulation performance at the side of the wall panel can be effectively improved. A non-metallic sealing strip 7 is bonded in the connecting groove 4. The non-metallic sealing strip 7 can be a continuous rubber and plastic sponge strip. With the setting of the non-metallic sealing strip 7, after two adjacent wall panels are connected by insertion, the non-metallic sealing strip 7 can seal the end faces of the two wall panels, thereby improving the connection sealing performance of the wall panels. This not only prevents rainwater leakage but also improves its thermal insulation performance.

[0026] The inner structure 1 includes a vacuum thermal insulation material 11 and a Class A fireproof insulation board 12. The Class A fireproof insulation board 12 is a rock wool board or a glass wool board. The vacuum thermal insulation material 11 and the Class A fireproof insulation board 12 are bonded together. The vacuum thermal insulation material 11 and the Class A fireproof insulation board 12 are bonded together with flame-retardant polyurethane foam adhesive or adhesive mortar.

[0027] The vacuum insulation material 11 includes a vacuum insulation board 111 and a slurry protective layer 112. The slurry protective layer 112 covers the surface of the vacuum insulation board 111 on all six sides to form the vacuum insulation material 11. By combining the vacuum insulation material 11 with the Class A fireproof insulation board 12, the vacuum insulation material 11 can effectively improve the thermal insulation performance of the wall panel. The Class A fireproof insulation board 12, while improving the thermal insulation performance of the wall panel, can also improve the sound insulation, earthquake resistance, and fire resistance performance of the wall panel, thus effectively enhancing the overall performance of the wall panel.

[0028] The vacuum insulation material 11 has one layer, and the Class A fireproof insulation board 12 has two layers. The two layers of Class A fireproof insulation board 12 are respectively bonded to the two end faces of the vacuum insulation material 11 to form the inner layer structure 1. By placing the vacuum insulation material 11 between the two layers of Class A fireproof insulation board 12, the vacuum insulation material 11 can be effectively protected, avoiding damage and failure of the vacuum insulation board 111 due to external impact, vibration, etc., thereby effectively improving the service life of the wall panel.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
